The range of a relation is

a: the output (y) values of a relation
b: the input (x) values of the relation
c: a set of points that pair input values with output values
d: x and y values written in the form (x, y)

Let M and N be 2 sets, 

Consider a relation R, from M to N
that is:

R:M→N
R(x)=y

so x is taken from set M, and the product y, is in set N

The set of all output of R,so all possible y, is called the Range of y:

 A: the output (y) values of a relation
